fib: implement RCU rule reclamation

Currently, for DIR24-8 algorithm, the tbl8 group is freed even though the
readers might be using the tbl8 group entries. The freed tbl8 group can
be reallocated quickly. As a result, lookup may be performed incorrectly.

To address that, RCU QSBR is integrated for safe tbl8 group reclamation.

fib: lookup IPv4 address in network order

Previously when running rte_fib_lookup IPv4 addresses must have been in
host byte order.

This patch adds a new flag RTE_FIB_F_NETWORK_ORDER that can be passed on
fib create, which will allow to have IPv4 in network byte order on
lookup.

Recent versions of doxygen (1.9.4 and newer) complain about
documented return types for functions that don't return anything.

This patch removes these return types to fix build errors similar
to this one:

Tested with doxygen versions: 1.8.13, 1.8.17, 1.9.1, and 1.9.4.

lib: remove librte_ prefix from directory names

There is no reason for the DPDK libraries to all have 'librte_' prefix on
the directory names. This prefix makes the directory names longer and also
makes it awkward to add features referring to individual libraries in the
build - should the lib names be specified with or without the prefix.
Therefore, we can just remove the library prefix and use the library's
unique name as the directory name, i.e. 'eal' rather than 'librte_eal'
